Capturing ACSII control characters GS,RS, EOT on web form.


Is there any way to capture the ASCII control characters GS, RS and EOT on the web form (input type=text)? It seems the web form strip-off the un-printable characters (ACSII control characters) from the input field.

txnguyen,

On just about any web implementation ASCII control characters will be stripped off.
To work around this the apply tilde functionality can be used to insert non printable ASCII characters.
For example setting Apply Tilde or Process Tilde to true and putting ~004 in the data string will encode an EOT character in the barcode.

The exact implementation can differ depending on the product. What specific product is being used to create the barcode?

Yes, we are using ~ + Ascii code for creating barcode with ASCII control characters, but HTML strip-out the ACSII when scanning the barcode to a text field on a web form. The problem is how to read barcode with ACSII control characters on the web form (HTML).
